Polyester Fiber 100% Wet-Laid Nonwoven Fabric

Polyester Fiber 100% Wet-Laid Nonwoven Fabric
TH Type

TH is a wet-laid nonwoven fabric made from 100% polyester. It comes in three types: 05TH with standard fibers, 15TH with thick fibers, and a super high-density type S. Each type offers specific features such as dimensional stability and resin impregnability. In particular, it demonstrates excellent thermal dimensional stability, smoothness, and resin adhesion, making it suitable not only for industrial use but also for a wide range of applications.​

Key Features

  • Basis weight customization
  • Thermal dimensional stability

Application Examples

Membrane products for gas and liquid separation

Membrane Products for Gas and Liquid Separation

The TH type, formed into thin films using proprietary technology from high-strength polyester fibers, functions exceptionally well as a support material for membranes. Its uniform structure in both width and length directions has earned high praise from customers, contributing to membrane products for gas and liquid separation.

Electromagnetic shielding tape – application example for TH type nonwoven fabric

Electromagnetic Shielding Tape

By applying a thin and uniform electromagnetic shielding layer through post-processing, this material demonstrates excellent performance as an electromagnetic shielding tape. Especially, the super high-density type achieves a density of 0.75 g/㎤ at a thickness of less than 20 μm, making it ideal for compact and lightweight mobile devices. *Left image: after plating process

Various types of industrial tapes – application example for TH type nonwoven fabric

Various Types of Industrial Tapes

With the characteristic uniform thickness and conformability of wet-laid nonwoven fabric, this material is highly suitable as a tape base. 05TH-8, with a thinness of 33 μm and low density, excels in adhesive impregnation, making it ideal as a base material for various industrial tapes.
